Reasons for Procedure

The median nerve runs from the forearm into the hand.
Carpal tunnel syndrome
occurs when this nerve is squeezed at the wrist as it runs through the carpel tunnel. This results in pain, weakness, tingling, or numbness in your hand and wrist. Pain may also radiate up your arm.

Steroid injections into the carpel tunnel area can help improve symptoms for 3 months or longer. You may not need further treatment.

Possible Complications

Complications are rare, but no procedure is risk-free. Your doctor will review a list of possible complications which may include:

Infection

No improvement in symptoms
